Question

The foot of a ladder is 6m away from a wall and its top reaches a window 8 m above the ground. If the ladder is shifted in such a way that its foot is 8 m away from the wall,to what height does its top reach....

Answer 1

Answer:

Its top will reach to 6m...

Step-by-step explanation:

According to question,

B = 6m, P = 8m

Using Pythagoras Theorem,

H²=P²+B²

H²= (8)²+(6)²

H= 10 m

This H = 10 m is the height of ladder that won't change...

Now,

B = 6m changes to B = 8m

Similarly applying Pythagoras theorem,

(Solve her for complete solution, it is skipped here...)

We get P = 6m

Therefore, the top reaches 6m above the ground...

Hope it helps....
